Email subjects need to be encoded

Currently the Cucumis system sends raw UTF-8 as email message subjects. This is a violation against email standards and can break things - at least illegal characters in subject field are causing spam filters, such as Spamassassin, to give Cucumis messages spam scores.

Subject fields with other than standard 7-bit ASCII characters should be encoded with quoted-printable before sending.

Hi ljon, thanks a lot for this remark.
Can you tell me more about "encoded with quoted-printable " ?
What am i suppose to do when the email subject is in arabic ?

The Subbjet: field is part of headers of the email message and only 7-bit ASCII is allowed there. The "Q" encoding that should be used is specified by RFC 2047, section 4.2 and the quoted-printable encoding that’s used by the Q encoding is specified by RFC 2045, section 6.7. A lot of information on this may be found with simple Google searches.

But I’m shure you don’t have to code this from scratch—I don’t know what programming language is used by Cucumis but funcions for this must be readily available at least for PHP, Perl and Python.
